The key insight (that older people count out seconds faster) is based on experimental science. The rest is more speculation.
FWIW, I'm convinced that seconds felt slower when I was a child, and they now tick up faster than they used to. Obviously there's no way to measure this, because this is my perception, not measurable reality.
